12 Claims. (01. 242-86) This invention relates to hose reels and is moreparticularly concerned with the provision of an apparatus adapted forstoring lengths of hose used in conjunction with lubricating and otherequipment of the type commonly found at automobile service stations.

At the better equipped automobile service stations, it is common to haveseveral lengths of hose which are used in conjunction with a variety oflubricating and other apparatus in the normal servicing of anautomobile. For instance, it is 3 usual to have a high pressurelubricating hose leading from a compressor to a coupler and valve. Thishigh pressure hose and coupler is used for lubricating the major portionof the lubricating fittings of a modern automobile. Additional hoselengths are connected to supply engine oil and one or more types of gearoil. In addition to the above mentioned hoses intended to dispenselubricants, it is usual also to have a radiator filling water-hose and atire inflating air hose.

The illustrated embodiment of my invention discloses a hose cabinetadapted to store uponseparate reels six different hose lengths. It willbe appreciated, however, that the invention is not limited to use withany particular number of hose lengths, since in larger service stationsit may be desirable to store more than six lengths of hose in anapparatus of the type comprising the present invention, while, insmaller service stations, a fewer number of hose lengths might beconsidered sumcient.

With the above in mind, it is an object of my invention to provide animproved hose cabinet for storing on separate reels a plurality of hosesof the type used in automobile service stations.

Another object of the invention is the provision of a novel automaticre-wind reel mechanism by means of which any one of several lengths ofhose can be unwound or rewound to any desired extent. 4

Still another object of the invention is to provide an improved hosecabinet having a plurality of hose reels so arranged that the hose onany one of the reels can be rewound independently of the other hoselengths by a single electric motor common to all of the reels.

An additional object is the provision of a novel hose cabinet having aplurality of hose reels so arranged that the hose lengths upon the reelsare permanently connected at their inner ends to a source of fluidsupply.

' Still another object of the present invention is the provision of animproved automatic re-wind hose reel which may be remotely controlled ina novel manner by means of the hose itself.

An additional object of the invention is the provision of an automaticre-wind hose reel having control means aflected by the hose such thatthe hose may be pulled freely from the cabinet and will remain in itsextended position even though the hose may become slack thereafter, butwhich will re-wind the hose when the hose is subjected to a slightmomentary jerk and which will cease re-winding the hose after the slackhas been taken up.

Still another object of the present invention'is to provide a novel hosestoring and retrieving ca'binet having the above characteristics andwhich is so constructed that it will not be likely to be subject tobreakdowns in service.

Yet another object of the present invention is to provide an improvedhose cabinet having the above desirable feature and which is adapted tobe constructed in units which may be easily assembled to form cabinetsof difierent sizes, so that, for instance, a hose cabinet adapted tocontain two hose lengths can beput into service and at a later date,additional cabinets to contain additional lengths of hose can be addedto the first unit without the necessity for supplying a separate motorand drive arrangement for the additionally supplied units.

Other objects and advantages will appear from the following descriptionof a preferred embodiment of my invention, reference being had to theaccompanying drawings in which:

In general, my hose cabinet comprises a motor driven line shaft whichextend through a plurality of (in the present instance three) individualhose cabinets. Each of these cabinets is provided with two reels andeachof these reels may be individually connected to the shaft by meansof individual sprockets and chains and a clutching arrangement forconnecting one of the sprockets to rotate with the line shaft. Thus, byengagement of one of these clutches, the rotating shaft can be connectedto drive the particular reel with which the clutch is associated so asto wind the hose length upon this reel.

In each instance, the inner end of the hose length is connected to afitting at the center of the reel which in turn is connected to a fluidsupply line by means of conduits, including a rotary seal. Anarrangement is also provided for completing the electric circuit to themotor when any one of the before-mentioned clutches is engaged. Thedisengagement of each of these clutches is controlled by a roller, whichis raised when the quantity of hose upon the reel exceeds apredetermined amount. This clutch is also controlled by a grooved rollermovable in a direction normal to its axi and over which the hose isdrawn while being extended. The latter roller is associated with theclutch control mechanism in such a manner that, as the hose is beingdrawn outwardly, the roller will be raised to a position which actuatesthe clutch in such a manner that it is disengaged from the line shaft. Adetent means associated with the clutch mechanism prea novelarrangement, permits the roller to be released by the detent means. thusens s l the clutch associated with this particular roller.Bimultaneously with the engagement of this clutch, the motor is started,thereby rotating the reel and retrieving the hose.

If it is wished to return the hose completely into the cabinet, theretrieving process instituted by jerking the hose is permitted tocontinue until the valve or other accessory at the outward end of thehose has been retrieved to it completely retracted p sition, at whichtime the clutch is disengaged and the motor stopped. If it is desiredmerely to retrieve a portion oi the outstanding hose, the operator Jerksthe hose to engage the clutch and start the motor in the mannerpreviously mentioned. After a portion of thehose has been rewound uponthe reel and the slack thus taken up, the hose becomes tight, thuslilting the grooved roller, previously mentioned, which is operative todisengage the clutch and stop the motor. After the clutch has becomedisengaged and the motor stopped, the hose may be permitted to go slackand no further retrieving of the hose will follow until the hose isagain given a slight Jerk.

Referring to Fig. 4 of the drawings in which a plan view of a six reelcabinet is shown, it will be perceived that this cabinet is made up of alefthand unit A, an intermediate unit B and a righthand unit C. Each ofthese units contains two hose reels and they are substantially identicalexcepting for the sizes of the reels and excepting for the fact that thecabinet. to the left is equipped vents movement of the grooved roller inthe oppowith a motor I44 and associated mechanism for driving all of thehose reels. Beginning at the left, these hoses in order are indicated bythe numerals 22, 24, 28, 28, 30 and 32, and respectively are connectedat their outer ends to a water valve 34, an engine oil dispensing andmeasuring gun 36, a pair of gear 011 dispensing and measuring guns 38and 40, a high-pressure lubricating gun 42, and an air chuck 44. It willbe appreciated that the particular sizes and types of hoses shown andthe dispensing accessories attached to the ends thereof are given merelyfor purpose of iilustration and that any one or all of these hoses anddispensing accessories could be replaced with hoses and accessories forother purposes.

Since each of the three individual units A, B and C is substantiallylike the others, a general description of the unit A will sufflce, whilethe manner in which the other units difler from this unit will bepointed out as the description proceeds.

The framework of the unit A is comprised of a pair of upstandinggenerally rectangular side plates 46 and 48 secured at their lower endsby means of angle iron strips 50 to front and rear transverselyextending channels 52. As best shown in Fig. 2, each of the units A, Band C is provided with side plates 46 and 48 and angle iron strips 50,although a single set of channels 52 extends beneath and connectstogether all of the separate units; similarly, the upper ends of theside plates 48 and 4| of the several units are connected together by atransversely extending box-like housing 54. This housing 54 addsrigidity to the structure and serves to house sets of grooved rollers 58between which the hoses are drawn. A pair of these rollers 58 isprovided in alignment with each of the hose reels to be describedpresently and serves to guide the hose as it is being withdrawn orretracted from the cabinet.

Directly above each set of these rollers, hose openings 31 are providedin the box-like struc-' ture 54 through which the hoses are drawn.Outwardly extending cuffs 58 surround these openings and support thedispensing accessories attached to the outer ends of the hoses inpositions away from the face of the cabinet.

In a position somewhat above their mid-points, the side panels 48 and 48carry a transversely extending shaft 60. The ends of the shaft are ofreduced diameter and are threaded and rigidly secured to the panels bymeans of nuts 62.

Spaced inwardly somewhat from its ends, the shaft 60 Journals a pair 01'reel hubs 04 and 86 in alignment with the slots 50. Each of these reelhubs is restrained against relative longitudinal movement by an annularinternal flange 68 formed within the hub and which provides shoulders 09that bear against the internal edges of annular packing retaining rings10. Outwardly of the rings 10, the annular space between the shaft andhub contains a quantity of pacmng ll confined by outer packing retainingrings 12. against a shoulder I3 on the shaft 80, while the outermostsimilar ring 72 is confined by a collar keyed to the shaft 60 and spacedfrom the panels 46 and 08 by tubular spacing elements 15. Opposite thecentral portions of the hubs 6B and (it, the shaft has sections ofreduced diameter forming annular recesses It between the shaft and hubswhich communicate by means of in tersecting bores I8 and BE in the shaftwith fluid supply conduits 82. Therefore, fluid under pressure in theconduit 82 passes through the intersecting bores 80 and 58, to therecess I6, and exerts pressure tending to force the rings 10 outwardly,thereby compressing the packing and sealing the junctures between theshaft and the hubs against leakage.

Both ends of the hubs 6t and 66 are secured to reel side plates M whichextend outwardly and are spaced apart a distance slightly greater thanthe diameter of the hose to be stored upon the reel. At intervals thetwo side plates are connected together at points spaced outwardlysomewhat from the hub by means of circumferentially arranged bolts 36and tubular spacers 88. These tubular spacers 88 serve to support theinnermost loop of the hose and in that capacity act as a rum upon whichthe hose is wound.

The inner end of the hose length 22 or is mnnected by means of asuitable coupling to an L-shaped fitting 90 which extends inwardly andis threaded into a, radially extending opening in the hub, which in turncommunicate with the annular recess it; thus fluid under pressure fromthe recess 78 passes outwardly through the fitting St and into the hoselength wound upon the reel. The L-shaped fitting 90 is of such a lengththat its outward end, which is connected to the inner end of the hoselength is in proper position so that the hose length extending at rightangles therefrom will pass around the next adjacent tubular spacingelement 88 without forming any substantial kink in the hose.

Each of the collars lid is secured to the center of an outwardlyextending spring metal arm 92. The two ends of these arms have frictionbrake shoes M which bear against the outer faces of the reel side platesand exert sufficient resistance to the rotation of the reels to preventthe reels from overrunning when the hose is being with drawn therefrom.

The innermost of the rings I2 abuts The outer ends of the bolts 00 arethreaded into bushings 30 which are attached to an annularsprocket 03 ofcomparatively large diameter. In a manner to be explained more fullypresently, a chain I00 passed over this sprocket is used to drive thereel in retrieving the hose into the cabinet.

From the hose reel indicated generally by the numeral I02, the hosepasses downwardly around an idling roller I 04, thence downwardly andrearwardly around a control roller I 06, thence upwardly and rearwardlybetween a pair of closely spaced rollers I00 mounted to rotate uponparallel axes, and thence upwardly and forwardly between the rollers 08at the mouth of the opening 51.

Of the above described rollers, those numbered I04, I00 and 56, rotateabout fixed axes, while, as will be described more fully presently, theroller I08 not only is rotatable, but also is movable in a directionnormal to its axis.

It will be appreciated that this arrangement enables the hose to befreely withdrawn from the cabinet. It is necessary merely to seize thedispensing accessory attached to the end of the hose and pull outwardly,the hose passing around the above-mentioned rollers and rotating thereel I02 against the braking action of the brake shoes 84 as it isunwound.

The roller I06 is journaled to rotate upon a pin I I0 projectingoutwardly from a position near the lower end of an,obliquely upwardlyand forwardly extending control bar II 2. In a position lower down uponthe bar IIZ, another pin H0, similar to the pin H0, journals a secondroller H6. This second roller is thus adjacent to and prevents the hosefrom slipping oh the first roller I08. A pair of plates H8 and I20 aresecured to the pins H0 and H 3 on the two sides of the rollers and aidin giving rigidity to the roller mountings and also aid in confining thehose length to the groove in the roller I06.

The control bar 2 is positioned adjacent the inner face of the sideplate 06 or 48, as the case may be, and is provided with alongitudinally extending slot I22 near its lower end, which is fitted toa rod I24. This rod extends transversely through the cabinet from sideto side and is secured at its ends to the side plates 46 and 08'.

At a mid-point in its length, the control bar IE2 has a econdlongitudinally extending slot 626 through which the shaft extends, whilenear its upward end in a position just below the top of the cabinet, athird longitudinally extending slot I28 embraces a pin I30 secured tothe side wall of the cabinet. By means of this pin and slot mounting,the bar H2 is free to move longitudinally within limits, but isrestrained against movement in other directions. 4

A switch bar I32 is located in the upper forward portion of the hosecabinet in a position just in front of the control bar II! and isjournaled to rotate in bearing members I33 attached to the cabinetsidewalls. This bar extends substantially the full length of themultiple hose cabinet and consequently its length is determined by thenumber of hose reels the cabinet contains. As will be seen in Fig. 4,which shows a cabinet containing 6 hose reels, this bar I32 extends fromend to end of the cabinet and passes above and in front of each of theseparate reels. At one end, a tilt type mercury switch I34 is secured tothe bar I32 by means of a spring clip I 36 so that angular displacementof the bar I32 will cause the mercury switch to tilt into either its onor off positions. A pin Ill projects downwardly-from the bar I32 and hasits outer end secured to one end of a coil spring I40, the opposite endof which is hooked to a stud I42 in the cabinet side panel. This springis under tension and tends to pull the outward end of the pin I38rearwardly and thus tends to tilt the mercury switch I04 into its offposition. Since this switch I84 is in a series circuit with a motor I44,which supplies the motive power for driving the hose reels, the motorwill not operate as long as this switch is in its oil. position.

Each of the control bars H2 is provided near its upward end with aninwardly extending U- shaped bracket I48. That is, one end of thisbracket is secured to the upper end of the control bar II2 by a capscrew I48. Directly below this cap screw the bracket I48 is bent toextend outwardly at right angles to the bar I I2 and extends in thisdirection a distance suflicient to carry this horizontal portion beyondthe adjacent hose reel. At this point the bracket extends at rightangles thereto downwardly parallel to the bar II2 into a position justbeyond the rim of the hose reel. From this point, the bracket extendsdirectly inwardly across the face of the hose reel and has its lower endsecured to the bar II2 by a second cap screw I50. A control pin I52 issecured to and extends directly outwardly from the lower end of thevertical portion of the bracket I48.

This pin I52 extend through a slot I54 in the free 1 end of a controlarm I58, which, at its opposite end, is bent into a U-shape at I51 andhas aligned apertures therethrough through which the control shaft I32extends.

Between the parallel arms of the. U, the shaft I32 is provided with aflat spot I58, which faces generally away from the pin I54. Anadjustable screw I80, held in place when adjusted by a lock nut I82 isthreaded through the central portion of the U-shaped portion I51 in aposition generally above the center of the shaft I32. This screw is nottightened against the flat spot I50 but is designed to provide suihcientlost motion between the end of this screw and the flat spot so that, asbest shown in Fig. 12, any downward movement of the free end of the barI58 from the position shown will cause the end of the screw I80 to abutagainst the flat spot I58 in a position above the center of the rod andcause the rod to turn in a counterclockwise direction. On the otherhand, any upward movement of the free end of the arm I58 will move theend of the screw I80 away from the flat spot and permit sufflcient lostmotion so that the arm I58 can be pivoted in this direction aconsiderable distance without the end of the screw I80 causing movemen.of the bar I32 in a clockwise direction.

Since the end ofthe bar I58 embraces the pin I52 secured to the controlbar II2, it will be seen that downward movement of any one of thesecontrol bars will cause its associated arm I58 to rotate the rod I32 ina counterclockwise direction against the tension of the spring I40, butbecause of the lost motion arrangement just described, this rotation ofthe shaft I48 will not be transmitted to any of the other control armsI58. Thus, when all of the control bars II2 are slid into their upwardpositions, the spring I40 will rotate the rod I32 and tilt the mercuryswitch I34 into its off position. On the other hand, if any one or moreof these control bar I I2 is permercury switch will be tilted into itson position and-will remain in its on position until all of the bars IIIare returned into their upward poitions.

One means for shifting the bars H2 in an upwardly direction already hasbeen described. This means consists of the rollers Ill around which thehose lengths pass, and associated mechanism. For instance, if it isconsidered that the bar 2 is in its downward position, and the hoselength is in the act of being pulled from the cabinet, the brakingaction of the reel tending to hold back on the hose, together with theoutwardmovement of the free end of the hose, will decrease the size ofthe loop in the hose between the rollers I04 and the rollers I08. Thisoutward movement of the hose, therefore, will lift the roller I08 andurge themar II2 upwardly. Similarly, if the end of the hose is heldstationary and the motor is driving the reel by a means to be describedpresently and thus retrieving the hose, when the hose becomes taut, theroller I08 will be lifted in a like manner.

From this, it will be apparent that whenever the hose is being pulledfrom the cabinet and whenever the hose is being retrieved into thecabinet and becomes taut because the end of the hose is held and thusnot permitted to move, the bar II2 will be shifted upwardly, and in themanner previously described, will tilt the mercury switch I34 into itsoflf position and shut off the supply of energy to the motor I44.

Another means for shifting the control bar upwardly is controlled by theamount of hose wound upon the reel and is in general so adjusted that itopens the electric circuit to the motor whenever the hose is fully woundupon the reel. This device includes a roller I84 journaled to rotateabout a pin I88, and positioned between the side 40 plates of the reelso that as the reel fills with hose, eventually the hose will impingeagainst the roller and lift it upwardly. This roller is mounted within arecess I88 in a plunger I10, the side walls of which carry the pin I88,and the plunger is in turn slidably mounted within an externallythreaded oval shaped member I12. Although the member I12 is aboveindicated as of oval shape, it may more properly perhaps be consideredas an externally threaded cylinder, opposite faces of which are cut awayso as to reduce the thickness of the member sufllciently so that it canbe inserted between the side plates of the hose reel, while at the sametime permitting a portion of the external threads to remain, by means ofwhich the member can be adjustably secured to the bracket I48.

This member I12 extends through an opening I14 in the lower horizontalportion of the bracket I48 and is clamped in place therein by means of apair of nuts I18 threaded to the external threads of the member I12.These threads are indicated by the numeral I18. By loosening one ofthese nuts and tightening the other, the vertical position of the memberI12 relative to the bracket I48 can be determined.

A pin I press fitted at its ends in the member I12 extends transverselythrough a slot I82 in the plunger I10 and limits the upward and downwardmovement of the plunger relative to the member I12. A coil spring I84located within a recess in the upper portion of the plunger I12 bearswith its opposite ends against the plunger and against the upper portionof the member mitted to move in a downwardly direction, the 1 I12 andthus tends to urge e plun e downwardly; This spring is-sufllcientlystiff so that when the hose impinges against the roller I84 and pushesthe plunger I upwardly, this movement will be transmitted through thespring and member I12 to'the bracket'l' ll i and bar II2 to open themotor circuit.- Thus the spring acts principally as a safety device toprevent the parts from becoming stressed unduly during the interval oftime required to stop the hose reel after the current to the motor isshutoff;

The drive for the hose reels includes the before-mentioned electricmotor I44 which is-connected by means of a V-belt I90 to a pulley I92.The pulley I92 is in turn keyed to one end of a line shaft I94 thatextends through all of the units of the hose cabinet and'is journaled torotate in bearings I98 positioned about the shaft where it passesthrough each'of the side panels.

Within each of the units the shaft I94 extends through a sleeve I98which carries certain members to be described presently and which isdriven by the shaft I94 through the medium of a key 200, held in placeby a cap screw 202.

At its left-hand end, as seenin Fig. 3, the sleeve I98 is provided witha sprocket 204 which drives-the previously mentioned roller chain I00.

The sprocket 204 is free to rotate relative to the sleeve I98 and isdriven from this sleeve by a clutch, indicated'generally by the numeral208, as best shown in Fig. 8. The clutch driven member 208 is mounted torotate with the sprocket 204 and carries a pair of outwardly radiatingwings 2 I 0. When engaged, these wings are driven by a pair of knobs2I2, which extend outwardly toward the left from a clutch driving member2I4. This clutch driving member 2I4 is formed as a portion of a collar2I8 slidably mounted upon the sleeve I98 butprevented from rotatingrelative thereto by a key 2I8. Therefore, when the collar 2| 6 isshifted toward the left,'the clutch will be engaged and the motor I44will drive the sprocket 204 and in turn the'reel I02.

A clutch shifting fork 220 extends into an annular groove 222 inthecollar 2I'8 and has its opposite end connected to ashiftingmember 224.This shifting member 224 is slidably mounted upon the bar I24 previouslymentioned. A collar 226 issecured to the bar I24 in a position inwardlyfrom the member 224 by means of a cotter pin 228 and serves toconfineoneend of a compression spring 230 coiled about the bar I24 and hearingwith its opposite end" against the inner end of the shifting member 224.This spring tends to urge the shifting member toward the left intoclutch engaging position.

Somewhat tothe left of the shifting fork 220, the shifting member 224-isprovided with a pair of oppositely disposed horizontally transverselyextending pins 232. Each of these pins is provided with a roller 234held in place by washers 238, and cotter pins 238 which extend throughapertures positioned near the outward ends of the pins. These rollersbear against a pair of cam faces 240 formed upon a cam 242 secured tothe lower end of the control bar H2.

The profile of this cam, which is best shown in Fig. 3, is so shapedthat when the control bar H2 is in its downward position, the upperportion of the cam face, which inthat position is in contact with therollers 234, permits the roller to move to the left sufllciently topermit the spring 230 to engage the clutch 206. Below this point the camface slopes obliquely to the right so that as the cam is lifted byupward movement of the control bars, the cam face' will cause therollers 234 to 'mov'e toithe right sufilciently to disengage theclutch206. Justbelow-thispoint, the cam face. is formedwith a re-entrantportion which acts as 'adetent; 243 to prevent the bar II2 from movingdownwardly. Thatis, as the bar H2 and cam 242 move upwardly, therollers234 will be moved toward the right until the re-entrant portionof-thecam-face is reached. Whereupon the spring 230 will move the rollers 234slightly to the left to act as detents resisting downward movement ofthe control bar I I2. This movement to the right, however, into thereentrant portion, is not sufficient to permit engagement of the clutch208. Just below the detent portion, the cam face again slopes obliquelyoutwardly toward the right to form a surface which urges the rollers 234still farther to the right as the cam and bar II2 are lifted upward- 1ybeyond the detent portion.

The pressure of the spring 230 is so adjusted that when .the rollers 234are in the detent portion-243, the bar II2'will be maintained in itsupward position. That is, the weight of the bar and its associatedmechanism tending to force the rollers 234 to the right is not as greatas the pressure of the spring 230. On the other hand, if the bar H2 islifted still higher so that the rollers 234 impinge against the portionof the cam face somewhat beyond the detent portion and then the bar H2is released and permitted to drop, the inertia of the dropping bar issufficient to carry the cam detent portion beyond the rollers and thuspermits the bar to drop'into its lowermost position.- Therefore, if thehose is pulled outwardly at the normal rate, the bar I I2 will be liftedin the manner previously described until the rollers 234 engage thedetent 243. In fact, the bar may be lifted somewhat beyond this point sothat the rollers pass beyond the detent means. In either event, afterthe hose has been withdrawn and is permitted to go slack, the bar I I2will settle at a comparatively slow rate and permit the rollers 234engaging in the detent. 243 to support the weight of the rod. II,

however, the hose is jerked suddenly, the bar II2 will be raisedsufficiently so that the cam will move upwardly into a position suchthat the rollers 234 are well beyond the detent 243. When the hose issuddenly permitted to go slack at the end of the jerk, the bar I I2 willfall rapidly and its inertia will carry the detent portion 243' beyondthe rollers 234 and permit the bar to go into its lowermost position. Ina'manner previously described, this movement of the bar 'I I2 into its.lowermost position causes the clutch 206 to be engaged, thereby causingthe motor I44 to rotate the reel and retrieve the hose.

Although in the above description of the lefthand clutch-and controlmechanism associated therewith, I have irequenth referred to parts asbeing to the right or left, it will be understood that adjacent hosereels and the controls and operating mechanism associated therewith arein general reverse complements of each other.

In order to protect the clutches and shifting mechanism at the lowerthese elements are partially enclosed within a sheet metal structure 248which also serves asan oil pan and which is provided near its centralportion with a d: JtiIl plug 248.

Referring to Fig. 1, it will be seen that the lubricant conduits 82enter the cabinet near the lower rear portion and pass generallyupwardly and inwardly to positions where they are connected to theshafts 80. In order to avoid crowdportions of the cabinets,

ing, some of these conduits pass upwardly a short distance .and thenobliquely upwardly and inwardly while others pass upwardly to a higherposition and then are curved, over in a loop and are attached to theupper surface of the shafts 60. Illustrated also in this figure is anelectric cord 250 for energizing the motor and having a plug! at itsfree end. This cord passes inwardly through the lower front edge of thecabinet and then passes upwardly through an armored conduit 254 to anoutlet box 2. Within the box 256 connections are made so that one wirepasses to the mercury switch I while the return wire from the mercuryswitch, together with the other wire from the conduit 254 passdownwardly through a second armored conduit 25! to the motor I.

From the above description of a preferred embodiment of my invention, itwill be seen that I have provided a device which accomplishes theobjects set forth at the beginning of the specification. A hose cabinetembodying the present invention is very convenient in use and requires aminimum of special operations on the part of the user in order toexercise control over its operation. When it is wished to withdraw ahose from the cabinet, it is necessary merely to take hold of theaccessory at the end of the hose and walk away from the cabinet. Anyslack that develops in the hose length during use of the dispenser atthe end thereof will not cause the hose to be retrieved into thecabinet. However, at any time it is desired to re-wind the hose, it isnecessary merely to subject the hose to a jerk.

After the hose has been retrieved into the cabinet, the clutches will bedisengaged and the motor stopped when the roller I64 is raised by theaccumulating hose upon the reel. At any point in the retrieving processthis action can be stopped by holding the hose until the slack has beentaken up, whereupon the clutch will be disengaged and the motor stoppedin a manner previously described in detail.
